Perhaps you should try some spelling variations:
2c radio » 2 radio, 22 radio, 28 radio
c radio » 2 radio, 7 radio, c ratio
2c tv » c tv, pc tv
2c tc » 2a tc, 2c c
23 tc » 23 tbc, 23 tci, 23 tcl
2b tc » 2b 2c, 2a tc, 2b t1

Try widening your search to All Fields.

You may be able to get more results by adjusting your search query.

• If you are trying to use Boolean operators, they must be ALL CAPS: %22print%((2c radio) OR (c radio))%((((((2c tv) OR (((((2c tc) OR (23 tc))) OR (2b tc))))) OR (27 tv))) OR (2c pv)) %_ cinema%22.
• The words AND, OR and NOT may confuse the search; try adding quotes: "%22print%((2c radio) or (c radio))%((((((2c tv) or (((((2c tc) OR (23 tc))) or (2b tc))))) or (27 tv))) or (2c pv)) %_ cinema%22".
• Adding a wildcard symbol may retrieve word variants: %22print%((2c radio) or (c radio))%((((((2c tv) or (((((2c tc) OR (23 tc))) or (2b tc))))) or (27 tv))) or (2c pv)) %_ cinema%22*.
